Does cel support regex syntax?

[SpecialYang]

Do we have a example for regex match?

@SpecialYang There's no syntax for regex specifically, but there is the matches member function with examples in the conformance tests of how to use it: https://github.com/google/cel-spec/blob/master/tests/simple/testdata/string.textproto#L110
